Cardano reaches important milestone and reduces parameter D to 0,5

IOHK CEO announces increased decentralization in Cardano after updating parameter d to 0.5.  IOHK will launch a blockchain industry effort to fight censorship on Wikipedia and update information on Cardano and Bitcoin.

IOHK CEO and inventor of Cardano, Charles Hoskinson, came up with a surprise Ask Me Anything (AMA) session. One of the main themes for the platform has been the beginning of its journey towards decentralization. Cardano has launched Project Catalyst and is actively developing the mechanisms of decentralization that will usher in his latest era, Voltaire.

In that sense, one of the most important announcements made by Hoskinson was the modification of the Cardano D parameter. After the change, this metric is set at 0.5, down from 0.52. This puts Cardano close to reaching an important milestone on his path to decentralization. IOHK’s CEO was pleased:

This means that half of all blocks will be made by the community, not the OBFT nodes. That’s a major achievement. At that rate of speed, it looks like D will drop to 0 around March (2021).

Parameter d has decreased in accordance with Cardano’s roadmap. This value was introduced after the deployment of the Shelley era. At that time, Cardano stopped being a federated state blockchain, on the Byron era. Therefore, the OBFT nodes stopped producing all the blocks to give participation to stake pools.

Block production is one of the three components that IOHK has highlighted to achieve Cardano’s decentralization. When parameter d is equal to 0, full decentralization will have been achieved. After D falls below 0.5, according to IOHK, decentralization will be “inevitable”.

IOHK effort to update information on Bitcoin, Ethereum and Cardano

On the other hand, Hoskinson also spoke about the long struggle they have had against censorship in Wikipedia. IOHK and the Cardano community have denounced in several opportunities that the content platform has modified or removed informa...
